Cryptocurrency Inheritance – What Happens To Your Cryptos When You Die?

Introduction

Ever imagined what would happen to your cryptocurrency when you die? In the case of land or property, it typically goes to the person’s children or to the ones mentioned by them. And all this happens legally with proper documentation. But it does not work the same way with a person’s cryptocurrency.

In cryptocurrencies, inheritance does exist but is pretty different from the regulated ones. Now, let’s understand the inheritance in cryptos keeping in the sense of the decentralization and anonymous nature of cryptocurrencies.

Though cryptocurrencies are not regulated officially, it does not mean you can let go off the unused coins. They do have value in themselves, and also if converted to fiat currencies. According to estimates, Bitcoins worth $20 billion is already lost and not in use. This could be due to negligence or the death of the owner without anyone’s knowledge that the person had coins in their portfolio.

Furthermore, a Reddit user created a spreadsheet accounting the wallet addresses, which were inactive since the time each Bitcoin was worth below $10. And in 2015, there were more than 3 million Bitcoins that were left untouched.

Ways to Not Let Cryptocurrency Unused

Dead Man’s Switch

In the case of cryptos, there exists a computer program that emails you at specific intervals and waits for your reply. If the program does not receive any reply from the sent email, it then automatically checks for death certificates of the account holder. If it finds such a record and does not receive any email, the program will transfer the coins in the wallet to the specified wallet mentioned by the account holder during the time of set up.

However, there is a downside to it. Even though it is helpful in cryptocurrency inheritance, there can be a scenario when an alive user does not reply to an email, and the computer protocol transfers away from the cryptocurrency to the specified address.

Doing the Traditional Way

This is a technique that does not require any kind of computer technology. This is the simplest inheritance issue where the user writes down all the wallet credentials and hands it over to their beneficiary. The credentials may contain the private key, exchange login detail, and the fiat currency accounts associated with it.

However, storing all the information in one place may not be the ideal option. It could turn out to be a very high price paid just for the convenience. Finally, it all drops down to trust. There must be trust between the account holder and the beneficiary. This is because the beneficiary could tamper with the credentials even before the death of the user. Hence, users must be choosy before handing over the details.

Conclusion

There are several ways to ensure that your coins are not buried with you and are handed over to your loved ones. But, with all of them, there exists a downside to it, which makes you think again on handing away the coins to someone. This has made cryptocurrency inheritance still tricky to deal with.

Beginners Guide To Atomic Swaps

Introduction

One of the features of cryptocurrencies is that they are decentralized. However, in reality, it is not completely decentralized. For the buying and selling of cryptocurrencies, the most popular option is to use a centralized exchange. Hence, adding an element of centralization in them.

Though this seems to be the best way to exchange cryptocurrencies, there are other better ways as well. This is because centralized exchanges sometimes possess big problems. There have cases where new exchanges have been hacked, which has caused losses for exchange and their clients. Moreover, the common issue with all exchanges is high withdrawal and trade fees. So, trading cryptos turns out to be expensive for clients with small capital.

Thus, the irony here is that cryptos that are known to be a peer-to-peer payment system requires users to go to a third party to exchange the coins. However, crypto analysts have taken this concern as a priority and have been able to come with something called “Atomic Swap.”

What is an Atomic Swap?

Atomic swaps are a solution to the above-discussed problem. Atomic Swap is a peer-to-peer exchange of cryptocurrency without the involvement of a middleman. If you are wondering what “atomic” means, it is a terminology used in computer science, meaning something would either completely happen or completely not.

Understanding Atomic Swaps

The main goal is to send someone cryptocurrency without the involvement of a third party. Let’s understand how the atomic swap makes this possible, with an example.

Assume Ron wants to send 1 Ether in exchange for 0.02 Bitcoins from Lisa. In atomic swap terms, we say that Ron has 1 ETH and wants to swap with Lisa for 0.02 BTC.

The key ingredient here is to create a smart contract called a hashlock. You may relate this to a container where the money is placed and is locked with a secret password.

How is the Hashlock made?

The hashlock, which is a smart contract that remains locked until the key is revealed, is made by Ron.

The hashlock is made using the following steps:

  1. A big random number is picked. It is called the primate. This is nothing but a secret password.
  2. This number is used to create another number called the A smart contract is created to send Lisa 1 ETH, locked with a hashlock created by him. This coin is accessible only when Lisa is able to figure out the preimage to the hash.

Note that calculating the hash from the preimage is easy, but determining the preimage from the hash is extremely challenging. In other words, Lisa cannot unlock the coins until she gets the preimage from Ron himself.

Role of Lisa

Now Lisa checks if she has received coins from Ron. This can be easily verified by checking on the public blockchain. After verification, Lisa creates a smart contract for 0.02 BTC with the same hash used by Ron.

Unlocking the coins

Now when Ron goes on to unlock the coins sent by Lisa, he uses the preimage he had created. But, in doing so, the preimage is recorded on the blockchain and becomes public information. Hence, Lisa can now use that preimage to unlock the coins sent by Ron.

Therefore, this completes the transaction without the involvement of a middleman.

This is a solution to the problem that exists in crypto exchanges. Since most users are still into exchanges, the idea of atomic swaps must be inculcated into exchanges and make them truly decentralized.
